The force behind Sunrise Moon, Misaki Akatsuki, posts a new Scene Clip tool for After Effects that will allow you to store a composition and restore it with the click of a button.
The After Effects script offers a simple panel that will show all the scenes that you have stored, or clipped. You can easily clip a scene at the press of a button. Scene Clip will add the composition to the panel and show you its preview.
Restoring is also done with a single click. Double clicking on any preview will let you instantly bring back the entire scene.
Sunrise Moon is responsible for other great After Effects scripts such as Align 3D, Marker Conductor and TranShape.
The script is free to download, so check out Scene Clip for After Effects here.
